OK, I am back again already, after promising to sign off.
I just looked at Wayne's link (listed above) to a different forum post on his setup. Wayne is doing with his load with what I am doing with the WDH. He has put a lot of the camping supplies on the back seat of his truck, which would put some weight back on the front axle. I betcha that generator is to the front of the bed also, again weighing down the front end some. He has figured out how to negate the need for the WDH by maximizing his load placement. Plus he has the HD package, which is essentially a 3/4 ton truck suspension.
Also, he has a 6.5 foot bed on a crew cab truck. I think most trucks reduce the bed length to 5.5 foot when the go to the crew cab vs. quad cab....that extra foot of interior is taken away from the front of the bed, still leaving the same wheel base.....I think, I think.
I am going to try signing off of here and get a life.
